Portable Graph Layout and Editing [PDF]
The Graph Layout Toolkit and the Graph Editor Toolkit are portable, flexible toolkits for graph layout and graph editing systems. The Graph Layout Toolkit contains four highly customizable layout algorithms, and supports hierarchical graphs.

Carving up the network of powers [PDF]
Do powers have parts? Mereological thinking is typically guided by two different metaphors: building vs. carving. The building picture treats wholes as constructed from fundamental bits; the carving treats wholes as the result of carving some ...

A Random Graph Model for Power Law Graphs [PDF]
We propose a random graph model which is a special case of sparserandom graphs with given degree sequences which satisfy a power law. This model involves only a small number of paramo eters, called logsize and log-log growth rate. These parameters capture some universal characteristics of massive graphs. From these parameters, various properties of the

Graph Powering and Spectral Robustness
Spectral algorithms, such as principal component analysis and spectral clustering, typically require careful data transformations to be effective: upon observing a matrix $A$, one may look at the spectrum of $ψ(A)$ for a properly chosen $ψ$. The issue is that the spectrum of $A$ might be contaminated by non-informational top eigenvalues, e.g., due to ...

Quotient graphs for power graphs [PDF]
In a previous paper of the first author a procedure was developed for counting the components of a graph through the knowledge of the components of one of its quotient graphs. Here we apply that procedure to the proper power graph \mathcal{P}_0(G ...

Measure preserving homomorphisms and independent sets in tensor graph powers [PDF]
In this note, we study the behavior of independent sets of maximum probability measure in tensor graph powers. To do this, we introduce an upper bound using measure preserving homomorphisms. This work extends some previous results concerning independence

The Edit Distance Function of Some Graphs
The edit distance function of a hereditary property is the asymptotically largest edit distance between a graph of density p ∈ [0, 1] and . Denote by Pn and Cn the path graph of order n and the cycle graph of order n, respectively. Let C2n*C_{2n}^* be

d-Path Laplacians and Quantum Transport on Graphs
We generalize the Schrödinger equation on graphs to include long-range interactions (LRI) by means of the Mellin-transformed d-path Laplacian operators.

Regularity of bicyclic graphs and their powers [PDF]
Let [Formula: see text] be the edge ideal of a bicyclic graph [Formula: see text] with a dumbbell as the base graph. In this paper, we characterize the Castelnuovo–Mumford regularity of [Formula: see text] in terms of the induced matching number of [Formula: see text]. For the base case of this family of graphs, i.e.
